The USA Player Series Cub preserves the purity of Bad Cat's original Cub circuit while offering increased flexibility. This improved design offers the ability to select between a 12AX7 or EF86 pre-amp tube using the mini toggle on the faceplate or the included footswitch. This new feature offers far more gain and versatility than previous Cub models. The kind folks at Bad Cat also added a selectable tone stack boost in both modes to give this pure single channel amp four unique gain stages. It can achieve everything from the traditional Cub 12AX7 chime to complex EF86 gain tones that were unachievable on earlier versions of the Cub. This ferocious feline is very lightly used, and we'll ship it to you super safe and super fast along with its tough Tuki slip cover! Feel free to give us a call with any questions you may have about it!
